For years there have been articles and videos about animals dying of plastic, either trapped by it or so full of it they can't absorb calories. Here's a quick Google search on necropsy photos animals with plastic in stomach. Most, but not all, are marine animals.

The back seat of my car is full of cloth tote bags for shopping. Even with those it is possible to end up with a lot of plastic making its way into the house. Around the US there are municipalities and counties that have outlawed the disposable bags. And of course pushback from some states that made laws saying their cities and counties can't ban them. Stupidity on the books.
